[PATCH] Update to clang-format script

[김규래]

GNU style brace wrapping rules have been added to clang-format quite a while ago.
http://llvm.org/viewvc/llvm-project/cfe/trunk/include/clang/Format/Format.h?revision=197138&view=markup
This simple patch proposes to use the built-in rules instead of the custom brace rules.
